This session will focus discussion on ways technology is a catalyst for development. In what ways can the development community find and support breakthrough solutions to the world's most important development challenges—interventions with the power to change millions of lives at a fraction of the usual cost? What might some of those interventions look like? What is the role of evaluation in identifying new technology, and what methods and platforms are useful to scales those activities? What are the biggest barriers to expanding the use of mobile technology solutions to the very poor?
